Abstract
Description
Le domaine de l'invention est celui des groupes électrogènes.The field of the invention is that of generating sets.
Plus précisément, l'invention concerne un groupe électrogène logé dans un conteneur insonorisé de dimensions standardisées, et plus particulièrement dans un conteneur de type « ISO 20' dry » conforme à la réglementation maritime CSC (de l'anglais « Container Safety Convention » pour « Convention Internationale sur la Sécurité des Conteneurs »), adopté par plus de 100 pays. Un tel conteneur est formé de deux parois longitudinales présentant une longueur de l'ordre de 6 mètres (soit 20 pieds) et de deux parois latérales présentant une largeur de l'ordre de 2,4 mètres.More specifically, the invention relates to a generator housed in a soundproof container of standardized dimensions, and more particularly in a container of the type "ISO 20 'dry" in accordance with the CSC (Container Safety Convention). "International Convention on Container Safety"), adopted by more than 100 countries. Such a container is formed of two longitudinal walls having a length of the order of 6 meters (20 feet) and two side walls having a width of the order of 2.4 meters.
Ces dimensions standard sont importantes, pour permettre un stockage et un transport aisé, parmi un ensemble d'autres conteneurs de mêmes dimensions, par exemple sur un navire.These standard dimensions are important, to allow easy storage and transport, among a set of other containers of the same dimensions, for example on a ship.
Il est connu d'utiliser des groupes électrogènes, soit dans des zones que le réseau de distribution électrique ne dessert pas, soit plus classiquement pour pallier une éventuelle coupure d'alimentation électrique. Dans ce cas, les groupes électrogènes sont principalement employés pour prévenir des situations où l'interruption de l'alimentation électrique entraînerait des conséquences graves ou des pertes financières, comme dans des hôpitaux ou des aéroports.It is known to use generators, either in areas that the power distribution network does not serve, or more typically to alleviate a possible power failure. In this case, the generators are mainly used to prevent situations where the interruption of the power supply would lead to serious consequences or financial losses, as in hospitals or airports.
Généralement, ces groupes électrogènes comprennent un moteur thermique et un alternateur relié à ce moteur thermique de manière à transformer l'énergie reçue du moteur thermique en énergie électrique.Generally, these generators comprise a heat engine and an alternator connected to this heat engine so as to transform the energy received from the heat engine into electrical energy.
Un inconvénient d'un tel dispositif est que, pour obtenir une puissance optimale, il est nécessaire de mettre en oeuvre au sein de ce dispositif des moyens de génération et de transformation d'énergie assez imposants, ce qui engendre donc une pollution sonore importante. Ce bruit généré n'est pas satisfaisant pour l'environnement qui est à proximité (par exemple les employés et patients d'hôpitaux).A disadvantage of such a device is that, to obtain optimum power, it is necessary to implement within this device means of generating and transforming energy quite large, which therefore generates significant noise pollution. This generated noise is unsatisfactory for the surrounding environment (eg hospital employees and patients).
Il est connu de placer de tels moyens constituant un groupe électrogène dans des conteneurs insonorisés. Ces conteneurs, généralement de dimensions standardisées sont formés de deux parois longitudinales, deux parois latérales, une base et une paroi supérieure, de manière à isoler les moyens de génération et de transformation de l'énergie, de l'environnement extérieur.It is known to place such means constituting a generator in soundproof containers. These containers, generally of standardized dimensions are formed of two longitudinal walls, two side walls, a base and an upper wall, so as to isolate the means for generating and transforming energy, the external environment.
Pour disposer de fortes puissances, les groupes électrogènes sont installés dans des conteneurs de 40 pieds (environ 12 mètres) de long, appelés « ISO 40' dry ». De tels conteneurs présentent un espace important, permettant d'éloigner les éléments les uns des autres, et d'optimiser l'évacuation de la chaleur et l'insonorisation. Cependant, ils présentent un encombrement important, qui n'est pas acceptable dans de nombreux cas.For high power, the generators are installed in containers 40 feet (about 12 meters) long, called "ISO 40 'dry". Such containers have a large space, to move the elements away from each other, and optimize the heat dissipation and soundproofing. However, they have a large footprint, which is not acceptable in many cases.
On peut alors utiliser un conteneur de 20 pieds, c'est-à-dire deux fois moins long. Mais dans ce cas, il n'est pas possible d'obtenir une très forte puissance. Par exemple, pour une température ambiante de 45° C, on ne peut obtenir une puissance supérieure à 1000kwe COP (puissance continue selon la norme 8528).We can then use a container of 20 feet, that is to say half the length. But in this case, it is not possible to obtain a very strong power. For example, for an ambient temperature of 45 ° C, it is not possible to obtain a power greater than 1000kwe COP (continuous power according to standard 8528).
En effet, l'utilisation d'un conteneur de cette dimension impose un confinement qui engendre une augmentation forte de la température à l'intérieur du conteneur.Indeed, the use of a container of this size imposes a confinement that generates a strong increase in the temperature inside the container.
En d'autres termes, un inconvénient d'un tel dispositif de l'art antérieur, est que la mise en oeuvre d'un groupe électrogène oblige à limiter la puissance développée, pour obtenir des nuisances sonores et thermiques acceptables.In other words, a disadvantage of such a device of the prior art is that the implementation of a generator forces to limit the power developed, to obtain acceptable noise and heat.
Encore une autre difficulté d'un tel groupe électrogène est que la Convention Internationale sur la Sécurité des Conteneurs (CSC) exige qu'aucun élément ne dépasse du conteneur ce qui empêche donc de développer un tel groupe possédant des moyens de refroidissement s'étendant à l'extérieur, par exemple sur le toit, afin qu'il soit conforme à la CSC. La CSC n'autorise pas non plus la présence d'éléments devant être démontés pour le transport maritime.Yet another difficulty of such a generator is that the International Convention on Container Safety (CSC) requires that no element exceeds the container thereby preventing the development of such a group having cooling means extending to outside, for example on the roof, to comply with the CSC. The CSC also does not allow the presence of items to be dismantled for shipping.
L'invention a notamment pour objectif de pallier au moins certains de ces inconvénients de l'art antérieur.The object of the invention is in particular to overcome at least some of these disadvantages of the prior art.
Plus précisément, un objectif de l'invention est, selon au moins un mode de réalisation, de fournir un groupe électrogène logé dans un conteneur de type « ISO 20' dry », qui permette d'obtenir une puissance relativement importante, et supérieure à celle disponible aujourd'hui pour un tel conteneur, tout en optimisant la dissipation de la chaleur dégagée.More specifically, an object of the invention is, according to at least one embodiment, to provide a generator housed in a container of the type "ISO 20 'dry", which allows to obtain a relatively large power, and greater than the one available today for such a container, while optimizing the dissipation of the heat released.
Ainsi, selon au moins un mode de réalisation, un objectif de l'invention est de fournir un tel groupe électrogène, apte à délivrer au moins 1200 kwe COP (puissance continue selon la norme 8528) à une température ambiante de 45° C.Thus, according to at least one embodiment, an object of the invention is to provide such a generator, capable of delivering at least 1200 kwe COP (continuous power according to standard 8528) at an ambient temperature of 45 ° C.
Un autre objectif de l'invention, dans au moins un mode de réalisation, est de fournir un tel groupe électrogène qui limite autant que faire se peut le bruit généré.Another object of the invention, in at least one embodiment, is to provide such a generator which limits as much as possible the noise generated.
Encore un autre objectif de l'invention est de fournir un tel groupe électrogène qui soit conforme à la CSC et qui, en outre, ne nécessite pas de démontage particulier pour le transport maritime.Yet another object of the invention is to provide such a generator which is in conformity with the CSC and which, moreover, does not require any particular disassembly for maritime transport.
Ces objectifs, ainsi que d'autres qui apparaîtront plus clairement par la suite, sont atteints à l'aide d'un groupe électrogène comprenant, dans un conteneur insonorisé de dimensions standardisées, formé de deux parois longitudinales présentant une longueur de l'ordre de 6 mètres, deux parois latérales présentant une largeur de l'ordre de 2,4 mètres, une base et une paroi supérieure, un moteur thermique et un alternateur relié audit moteur thermique pour pouvoir transformer l'énergie reçue dudit moteur thermique en énergie électrique.These objectives, as well as others which will appear more clearly later, are achieved by means of a generator comprising, in a soundproof container of standardized dimensions, formed of two longitudinal walls having a length of the order of 6 meters, two side walls having a width of the order of 2.4 meters, a base and an upper wall, a heat engine and an alternator connected to said engine to be able to transform the energy received from said engine into electrical energy.
Selon l'invention, le groupe électrogène met en oeuvre deux circuits de circulation d'air, à savoir :
- un premier circuit de refroidissement des puissances rayonnées par ledit moteur, comprenant :
- au moins trois entrées d'air distribuées sur un premier côté dudit conteneur, sur une première desdites parois latérales et lesdites parois longitudinales ;
- au moins deux éléments de distribution de l'air reçu via lesdites entrées d'air, délivrant l'air vers ledit moteur et ledit alternateur respectivement en partie basse et en partie haute dudit conteneur ;
- au moins deux premières sorties d'air, formées dans ladite paroi supérieure, sur le second côté dudit conteneur, au voisinage d'au moins un silencieux d'échappement dudit moteur, ledit silencieux étant monté sensiblement verticalement, de façon à être refroidi par l'air dirigé vers lesdites sorties ;
- un second circuit de refroidissement thermique dudit moteur, comprenant :
- au moins trois radiateurs, distribués sur le second côté dudit conteneur, respectivement sur la seconde desdites parois latérales et lesdites parois longitudinales ;
- au moins une seconde sortie d'air, formée dans ladite paroi supérieure, sur le second côté dudit conteneur ;
- au moins un ventilateur d'extraction d'air, monté au voisinage de ladite sortie d'air.
- a first cooling circuit of the powers radiated by said engine, comprising:
- at least three air inlets distributed on a first side of said container, on a first of said side walls and said longitudinal walls;
- at least two air distribution elements received via said air inlets, delivering air to said engine and said alternator respectively in the lower part and in the upper part of said container;
- at least two first air outlets, formed in said upper wall, on the second side of said container, in the vicinity of at least one exhaust muffler of said engine, said muffler being mounted substantially vertically, so as to be cooled by the air directed to said outlets;
- a second thermal cooling circuit of said motor, comprising:
- at least three radiators, distributed on the second side of said container, respectively on the second of said side walls and said longitudinal walls;
- at least a second air outlet, formed in said upper wall, on the second side of said container;
- at least one exhaust fan mounted in the vicinity of said air outlet.
Ainsi, l'invention propose une approche nouvelle et inventive de mise en oeuvre de moyens de refroidissement en combinaison, dans un conteneur de type « ISO 20' dry » conforme à la CSC, permettant d'obtenir un refroidissement efficace, malgré les faibles dimensions du conteneur, et donc une puissance améliorée, supérieure à celle disponible dans les groupes électrogènes de l'art antérieur.Thus, the invention proposes a new and inventive approach to the implementation of cooling means in combination, in a container of the "ISO 20 'dry" type conforming to the CSC, making it possible to obtain efficient cooling, despite the small dimensions the container, and therefore an improved power, greater than that available in the generators of the prior art.
Un avantage d'un tel groupe électrogène est en effet que la puissance générée est optimisée, pour une mise en oeuvre dans un conteneur standardisé compact, aisément transportable et gerbable.An advantage of such a generator is that the power generated is optimized, for implementation in a standardized compact container, easily transportable and stackable.
Dans un mode de réalisation de l'invention, le groupe électrogène met en oeuvre deux silencieux d'échappement, dont les sorties sont définies dans la paroi supérieure de façon à être chacune placée entre deux des premières sorties d'air.In one embodiment of the invention, the generating set uses two exhaust silencers whose outputs are defined in the upper wall so as to be each placed between two of the first air outlets.
Dans un autre mode de réalisation de l'invention, le groupe électrogène met en oeuvre deux ventilateurs d'extraction de l'air.In another embodiment of the invention, the generator set uses two fans for extracting air.
Selon une mise en oeuvre du groupe électrogène, le ou les silencieux d'échappement sont séparés dudit moteur par une cloison.According to one implementation of the generator, the exhaust silencer or silencers are separated from said engine by a partition.
Le groupe électrogène peut également comprendre un boîtier de commande, logé dans le premier côté du conteneur.The generator may also include a control box, housed in the first side of the container.
Dans un mode de réalisation de l'invention, le groupe électrogène comprend au moins un filtre à air, placé au-dessus du moteur.In one embodiment of the invention, the generating set comprises at least one air filter, placed above the engine.
Dans un autre mode de réalisation de l'invention, le groupe électrogène délivre une puissance d'au moins 1200 kwe COP à une température ambiante de 45°.In another embodiment of the invention, the generator delivers a power of at least 1200 kwe COP at an ambient temperature of 45 °.

Selon l'invention, deux circuits distincts de circulation d'air, à savoir un premier circuit de refroidissement des puissances rayonnées par le moteur, et un second circuit de refroidissement thermique du moteur, sont définis de façon particulière et optimisée. Le moteur et l'alternateur délivrent ainsi une puissance importante, par exemple de 1200kwe, et génèrent une chaleur importante par effet Joule qui est réduite selon l'invention par les premier et second circuits de refroidissement, de sorte que le refroidissement, dans l'exemple ci-dessus, permette un fonctionnement normal à une température ambiante d'environ 45 degrés Celsius.According to the invention, two separate air circulation circuits, namely a first cooling circuit of the powers radiated by the engine, and a second thermal cooling circuit of the engine, are defined in a particular and optimized manner. The engine and the alternator thus deliver a large power, for example of 1200 kW, and generate a large Joule effect heat which is reduced according to the invention by the first and second cooling circuits, so that cooling in the example above, allow normal operation at an ambient temperature of approximately 45 degrees Celsius.

Comme énoncé précédemment, le groupe électrogène comprend donc deux circuits de circulation d'air, à savoir un premier circuit de circulation de l'air pour le refroidissement des puissances rayonnées par le moteur, et un second circuit de circulation de l'air pour le refroidissement thermique du moteur (culasse et carter-cylindre notamment).As stated above, the generator thus comprises two air circulation circuits, namely a first air circulation circuit for cooling the power radiated by the engine, and a second air circulation circuit for the air. thermal cooling of the engine (cylinder head and crankcase in particular).
Le premier circuit de refroidissement des puissances rayonnées par le moteur comporte, en plus des quatre entrées d'air A1, A2, A3, A4 distribuées sur le premier côté du conteneur, deux éléments A5, A6 de distribution de l'air reçu par les entrées d'air. Les quatre entrées d'air permettent le passage des flux d'air AE et les acheminent vers les éléments de distribution A5, A6. Ces éléments de distribution dirigent ensuite l'air vers le moteur et l'alternateur, par exemple sous la forme d'un flux d'air AH en partie haute du conteneur et d'un flux d'air AB en partie basse du conteneur.The first cooling circuit of the powers radiated by the engine comprises, in addition to the four air inlets A1, A2, A3, A4 distributed on the first side of the container, two elements A5, A6 of distribution of the air received by the air inlets. The four air inlets allow the passage of AE air flows and route them to the distribution elements A5, A6. These distribution elements then direct the air towards the engine and the alternator, for example in the form of a flow of air AH at the top of the container and an air flow AB at the bottom of the container.
De cette manière, une grande surface du moteur et de l'alternateur est refroidie par les flux d'air AH, AB. Les flux d'air AH, AB, qui se sont réchauffés au contact du moteur, sont ensuite dirigés vers le local silencieux 7, défini par la cloison d'isolation 71 séparant les silencieux du moteur. Cette cloison, illustrée par la
Lors de leur cheminement vers les sorties A10, A11, les flux d'air AH, AB circulent le long des deux silencieux d'échappement 131, 132 de manière à les refroidir également. Les deux silencieux 131, 132 sont montés verticalement de manière optimiser l'encombrement et à être refroidi sur toute leur longueur par les flux d'air montant vers les sorties A10, A11. Ces deux silencieux possèdent chacun une sortie d'échappement 133, 134 de sorte qu'ils puissent éjecter les gaz d'échappement du moteur 10. Dans ce mode de réalisation, les sorties des silencieux sont définies au niveau de la paroi supérieure de façon à être chacune placée entre les deux sorties d'air A10, A11 du premier circuit de refroidissement.On their way to the outlets A10, A11, the air flows AH, AB circulate along the two
Le second circuit de circulation de l'air pour le refroidissement thermique du moteur comporte trois radiateurs R1, R2 et R3, distribués sur le second côté du conteneur, à savoir un radiateur R1 sur la paroi longitudinale droite, un radiateur R3, sur la paroi latérale avant, et un radiateur R2 sur la paroi longitudinale gauche.The second air circulation circuit for thermal cooling of the engine comprises three radiators R1, R2 and R3, distributed on the second side of the container, namely a radiator R1 on the right longitudinal wall, a radiator R3, on the wall front side, and a radiator R2 on the left longitudinal wall.
Ces trois radiateurs définissent une surface de refroidissement optimisée, dans un espace limitée, et refroidissent le moteur par l'intermédiaire d'un circuit de circulation. Ce circuit comporte une première portion 12 de circulation d'un fluide à basse température (refroidi par les radiateurs) qui est dirigé des radiateurs vers le moteur. Ce fluide se réchauffe au contact du moteur, abaissant en conséquence la température de ce dernier, et est renvoyé vers les radiateurs par une seconde portion 14 du circuit de circulation de fluide à haute température.These three radiators define an optimized cooling surface, in a limited space, and cool the engine through a circulation circuit. This circuit comprises a
Dans ce mode de réalisation, le fluide de refroidissement contenu dans le circuit de circulation est de l'eau glycolée.In this embodiment, the cooling fluid contained in the circulation circuit is glycol water.
Le passage du fluide à basse température au niveau du moteur permet donc de refroidir ce dernier et a pour effet direct de réchauffer le fluide. Quatre ouvertures 121, 122, 141, 142 ménagées dans la cloison 71 permettent à la première portion du circuit de circulation 12 et à la deuxième portion du circuit de circulation 14 de diriger le fluide du moteur vers les radiateurs et inversement. Ces quatre ouvertures correspondent respectivement à l'entrée moteur 121 de la première portion (basse température), la sortie moteur 122 de la première portion, l'entrée moteur141 de la seconde portion (haute température), et la sortie moteur 142 de la seconde portion.The passage of low temperature fluid at the engine thus allows the latter to cool and has the direct effect of heating the fluid. Four
Le fluide réchauffé passe d'une température haute à une température basse en étant refroidi par l'air entrant BE dans les radiateurs R1, R2 et R3.The heated fluid changes from a high temperature to a low temperature by being cooled by the incoming air BE in the radiators R1, R2 and R3.
Le second circuit de refroidissement comprend en outre deux ventilateurs d'extraction B10 situés, dans ce mode de réalisation, à l'extrémité de la paroi supérieure 6, du second côté du conteneur. Ces ventilateurs permettent d'accélérer et de contrôler la circulation du flux d'air BE traversant les radiateurs R1, R2 et R3 et ainsi d'optimiser le refroidissement du fluide circulant dans les radiateurs ainsi que le moteur.The second cooling circuit further comprises two exhaust fans B10 located, in this embodiment, at the end of the
Bien évidemment, de nombreux autres modes de réalisation sont envisageables. On peut par exemple prévoir un nombre différent d'entrées d'air du premier circuit de refroidissement. On peut en outre prévoir une disposition différente de ces entrées d'air.Of course, many other embodiments are possible. For example, it is possible to provide a different number of air inlets of the first cooling circuit. It is also possible to provide a different arrangement of these air intakes.
Par ailleurs, on peut imaginer un mode de réalisation de l'invention dans lequel le nombre de radiateurs ou la distribution de ceux-ci sont différents de ceux du mode de réalisation présenté. On peut en outre prévoir un nombre supérieur de secondes sorties d'air ou de ventilateurs.Moreover, it is possible to imagine an embodiment of the invention in which the number of radiators or the distribution of these are different from those of the embodiment shown. In addition, a greater number of second air outlets or fans can be provided.
